To all whom it may concern: I

Be it ,known that I, LORNE A. GRIFFIN, a citizen of the United. States,residing at Evanston, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Ash-Conveyers, of whichthe following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a provideelaborate or special devicesfor sup:

porting the conduit elements other than the one which it is necessary toremove.

In ash conveyor conduits as heretofore constructed, the removal of oneor more elements of the conduit removes the support of one or more ofthe elements of the conduit which are not removed, so that it has beennecessary to provide elaborate and special devices for temporarilysupporting the conduit structure when one or more elements were removed.This difficulty has been particularly serious when it has becomenecessary to remove a conduit, element forming a part of a vertical runof such a conduit.

These and other features of my invention are fully set forth in thefollowing description wherein reference is made to the accompanyingdrawings, in which-' Figure l is a vertical sectional view illusvtrating portlons of horizontal-and vertical.

runs of an ash conveyer conduit, together with a sectional right angleelbow affording communication between the same.

Fig; 2 is a fragmentary elevational view illustrating a modification ofthe arrangement shown in Fig. 1.

Fig. 3 is a view similar .to' Fig. 1 illustrating a conduit wherein thesections of which the horizontal and vertical runs are formed aresemi-cylindrical inshape.

Fig. 4 is a fragmentary elevational view illustrating modification ofthe arrange ment shown in Fig. '3.

Fig. 5 illustrates the application of my invention to an arrangementwherein the vertical portion or user of the condult comprises twoseparate" passages, and

F1 6 1s a horlzontal sectional VlBW' taken on t e line 6-6 of 5and'looking in the direction indicated the arrows.

Referring first to Fig. 1, the reference numerals '10 and 11respectively indicate vertical and horizontal portions of a conveyerconduit which are connected by a right angle elbow '12. It willibeunderstood that that part of the horizontal portion of the conduit whichhas not'been shown leads from the boilers or other point'from which theashes are to be conveyed and is provided with suitable hoppers-forintroducing the ashes into the conduit. It will also be un derstood thatthe vertical portion of the conduit leads ofl' to an ash tank, or to anypoint where the ashes are to be deposited. Furthermore, if the system isof the steam jet type, the conduit at one or more points isprovided witha nozzle for discharging steam under pressure into the conduit in thedirection of travel of the ashes to carry the latter throughthe'conveyen, Since my present invention is concerned solely'with theconstruction and arrangement of the several parts of the conduit, I havenot deemed it necessary to illustrate the hoppers, ash tank and steamjets in the figure now under consideration.

The vertical portion of the conduit illus trated at 10 comprises aplurality of sections, a, b, 0, etc., and a-d, b- -Zz, 0-0, etc. Theelbow '12 comprises the curved section an and the bottom and'endsections designated' as y and a respectively, the several abutting edgesof said elbow sections being connectedftogether by bolts 13 cooperatingwith apertured lugs 14.

Attention-is directed tothe fact that'each i of the sectionsa, 6, etc.,and aa, b-b,

etc., of'which the vertical run of the con-.

duit consists, comprise two portions one of 'which has a circumferenceof a litt1e more than 180, the other portion being a little less than180in circumference. Therefore,

in elevation, these pipe sectionsappear tobe substantially L -sh'aped.

t w l b in tedthat th upper portion f the curvedelbow section :1: andthe intermediate shoulders of the elbow section a are conformed tocooperate with the lower end of the vertically, disposed section a,

the upper portion of the elbow section 2 cooperating with the lowerportion of the section a-a to provide a cylindrical passage up as far asthe-intermediate shoulders of the section a. The upper half of the elbowsection 2 lies flush with the intermediate shoulders of the section a,and thus provides'an'annular surface to receive the lower portion of thesection a-a' which cooperates with the upper portion of the section a'to continue the cylindrical passage up as far as the upper end of thesection a.

' The section b resting upon the annular support afiorded by the upperend of the sec tion a and the intermediate shoulders of the section a"acontinues the cylindrical passage up as far as the upper end of thesection a-a. The cylindrical passage is continued upwardly by L-shapedsections b'b, a, c0, etc., all'cooperating in the manner just described.

It will be noted that no one ofthe several sections of the cylindricalportion of the conduit depends solely upon any other section for itssupport. Thus, for instance, section a is-supported bythe elbow sectionas and by the intermediate shoulders of the elbow section 2. Similarly,conduit section aa issupported by the upper end of the elbow section zand by the intermediate shoulders of the section a.- 7 All of the othersections of the vertical portion of the conduit are, similarlysupported, no one depending solely upon any other section for itssupport. W

So far as my present 1I1Ve1'lt/10I]. 18 concerned, the horizontal run ofthe conduit ,is desirably, but of course not necessarily,

. of the kinddescribed and claimedinpatent to James A.-Da.viess No.1,278,869, and of course it will be understood that I contemplatescoringany of the grouted joints as described in the Daviess patent if thatshould be necessary or desirable.

1 The grouted or other suitably packed.

joints between the ends of theconduit sections and the surfaces adjacentthereto are trated.

protected by semi-circular bands- 15-15, the bands of each pair beingsecured together b suitable bolts 16-16 'as illusgrouting or otherpacking material in position, and also serve to retain the severalconduit sections in proper relation to each:

. other.

With the arrangement herein shown, any section of the vertical portionof the conduit may be removed without withdrawing sup-'- hese bandsserve to retain the port from any of the other sections. For

instance,.assume that section b is to be removed .for inspection,replacement or re-- I 7 pair. All that need be done is to clamp thebands 6 and f in the positions shown in dotted lines, remove the band dand loosen the grouting or packing material adjacent the edges of thesection b. Section I) may then be removed without disturbing therelation of the other elements, since the section aa which rests on thetop of the elbow section 2 and the section a now carries the weight ofall of the sections'which lie above the removed section b. V i

The. modified construction illustrated in Fig. ,2 is substantially likethat shown in Fig. 1', and similar reference characters have 1 beenapplied to corresponding parts. The

arrangement shown in Fig. 2 differs from that shown in Fig- 1 mum theseveral sec- 7,

t-ions constituting the vertical portion of the conduit are providedwith lugs 17-17 which are secured together with bolts 18 to 100,

provide a, slightly more rigid structure. The several semi-cylindricalclamping bands 15 in this construction serve merely to hold the groutwhich is put in place between the opposing ends of the adjacent sectionsin position. In removing one of the L-shaped sections of thisarrangement, it is necessaryonly that the three clamping bands asseciatedwith that section be removed. The

four bolts,'two on eachfside of the conduit, 7

are then removed and the section taken out of the conduit for repairs orreplacement. In the modified arrangement shown in Fig; 3, tl ieseveralpipe sections of which the conduit is formed are made semi-cylindricaland are secured to one another by the sev- 10&

eral clamping bands shown'at 1515. The

elbow -20 affording communication between horizontal'conduit 21 and thevertical cons duit 22 is preferably made of several sec! tions asillustrated, which are clampedor secured together by the lugs and boltsshown at 2323. Grout is interposed between the longitudinal edges 24 andbetween the opposing ends 25 of the several sections, as

the case in the structure shown in Fig.1. In this construction thehorizontal partl'of or sections which are'identical with those whichconstitute the vertical conduit. If one of the sections, as for examplethe secthe conduit is preferably made up of units ing bands It and i aremoved to the positions indicated by thedotted lines and securely clampedaround the conduit. The

clamping band j is then removed from the conduit and the groutinterposed between the section 9 and the adjacent sections removed. Thesection 9 may then be removed laterally and repaired or replaced by anew section. Similarly, any one or more of the sections constitutlng thehorizontal run of the conduit may be removed and replaced.

The arrangement shown in Fig. 4 issimilar to that shown in Fig. 3,except that each of the several semi-cylindrical sections is providedwith aplurality oflugs through which the bolts 26 pass for the purposeof attaching the several sections to adjacentsections. The clampingbands 15 in this arrangement serve merely to hold the grout or filler inplace between adjacent ends of the pipe sections. In removing one of thesemicylindrical pipe sections employed in this construction, theclamping bands 15 associated with the section to be removed aredisconnected from the conduit, and the bolts 26 holding that particularsection removed. The section may then be removed as shown in thisfigure. I

In all of the foregoing arrangements the vertically extending conduitcomprises a plurality of pipe sections or units which cooperate to formsingle continuous passageway or conduit, but I may arrange the severalsections to form two or more conduits positioned immediately adjacentone another and each serving to support the other. In Figs. 5 and 6 Ihave shown such an arrangement. In these figures 27 designates thehorizontal run of pipe and 28 and 29 are vertical runs which communicatewith the horizontal conduit as shown. pivoted at 31 and operated byweighted lever 3:2 is employed for thepurpose' of atfordingcommunication between the horizontal conduit and either one of thevertical conduits 28 and 29.

In this arrangement the several sections which make up the vertical pipesections 28 and 29 may be either whole sections'as illustrated in thesefigures, Or semi-cylindrical sections as shown in Figs. 1 to linclusive.

Each semi-cylindrical section is provided with two ormore lugs 3333,which cooperate with the bolts 3434c for the purpose of locking theseveral sections of different conduits to one another. If it is foundnecessary or desirable to remove one" of the sections in thisconstruction, as for example, the section shown at k, thetwo clampingbands fitting over the ends of this section are removed, as are thebolts cooperating with this particular section. The grout interposedbetween the section I: and the adjacent sections is then removed and.

A gate 30 I the section moved laterall out of the conduit. e

In the use of this construction, the operation of the conveyer systemneed not'be discontinued during the repair or replacement of any one ofthe sections forming a part of either one of the vertical conduits 28and 29. For example, when the section k is removed, the gate 30 is movedto the dotted line position so that it discontinues communicationbetween the horizontal conduit 27 and the vertical conduit 29. A steamnozzle shown opposite the conduit 28 is then put in operation and theconduit 28 employed for transporting the ashes.

From the above description it will be observed that I provide a verticalconduit made up of several sections, the sections being disposed in. twoor more vertical rows, the sections of one row being connected withsections of a second row, whereby any section may be removed from anyrow without the necessity of providing some auxiliary support forholding the sections above that removed. The several arrangements shownin the accompanying drawings are self-supporting, and continue to be soeven though any one of the sections forming part of the vertical conduitis removed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. A self-supporting vertical conduit for ash conveyers comprising aplurality of sections arranged in two vertical rows and means forconnecting the sections of different rows whereby a section of one ofsaid rows may be removed.
